' SPRING JAWED PAPER CLIP I Filed Dec 22, 1959 2 Sheets-Sheet 2 VENTOR ATTORNEY Patented Feb. 4, 1941 UNITED STATES PATENT OFFICE 8 Claims.

This invention relates to temporary binders or binder clips of the spring jawed type. One of the objects of this invention is to provide a clip structure in which the jaw actuated arms are pivoted inside the clip body and extend outwardly through recesses therein to be capable of being folded so as to extend longitudinally of said clip body and permit the folding or rolling of the bound papers around the clip body without causing mutilation thereof.

Another object of this invention is to provide such clip with suitable auxiliary means whereby the folded or rolled papers can be retained in folded or rolled up condition.

With these and other objects in view which will appear from the detailed description of my invention, the latter substantially consists in the novel construction, combination and arrangement of parts as will be hereinafter more fully described and defined in the appended claims.

In the accompanying drawings which form part of this specification and in which similar reference characters denote corresponding parts,

Figure 1 is an end view of a C-shaped paper clip constructed according to my invention;

Figure 2 is a side View of said C-shaped paper clip;

Figure 3 is an end View of a modified C-shaped paper clip;

Figure 4 is a side view thereof;

Figure 5 is a cross section of another modification of said G-shaped clip;

Figure 6 is an inner face view of a detail of said last-named paper clip;

Figure 7 is an end view of a still other modification of said C-shaped clip;

Figure 8 is a perspective view of said lastnamed clip showing the clamped papers rolled around and retained on said clip by auxiliary means provided on the actuating levers of said clip; and

Figure 9 is an end view thereof.

Referring to the drawings more in detail and first to the construction shown in Figures 1 to 2, the temporary binder or fastener is of the conventional C-shape or in form of a split cylindrical shell I4, provided circumferentially with two parallel longitudinal slits or recesses I5 on opposite sides of the longitudinal axis of said shell. Mounted in said cylindrical shell are two oppositely arranged plates I6 whose forward edges extend outwardly through the split end [4a of the shell and form the jaws of the clip, and whose rear ends are formed with tongues or lips I! which fit in the slits I5. The actuating arms I8 have their inner ends pivoted to said plates I6 as at H511, and project outwardly through said slits or recesses I5, so as to be capable of swinging in the same direction laterally, to extend longitudinally of the cylindrical shell, as indicated 5 by dotted lines in Figure 2. In this position they permit the papers engaged by the jaws I6 of being rolled or folded around the clip I4 without any danger of mutilation.

In the modification shown in Figures 3 and 4 the construction is similar to that shown in Figures 1 and 2, except that here instead of the jaws being formed by separate plates IS the same are formed by bending the split edges of the spring shell I I inwardly to form abutments I9 to which the actuating levers or arms I8 are pivoted as at I9a, I91) so as to be capable of swinging in opposite directions as indicated by dotted lines in Figure 4. The outer ends of these arms project through the slits I5 of the cylindrical shell I4.

In the modification shown in Figure 5 instead of bending the split edges of the shell I4 in- Wardly to form abutments, blocks 20 of fibre, wood or other suitable material may be used. These blocks 20 are mounted inside the spring shell I4 and have their outer faces cylindrically curved to bear on opposite faces of said shell and are suitably centered thereon. The actuating levers I8 are pivoted to said block 20 by rivets 2I passed through the latter and the shell. The outer faces of said blocks are substantially flat and formed with grooves 20a, through which the levers I8 which project outwardly through the slits I5 are permitted to swing laterally on their pivots to extend longitudinally of the shell in the same manner as those shown in Figure 4.

In the modification according to Figures 7 and 8 the actuating arms I8 of the spring clip I4 are pivoted inside the latter to abutments I9 formed by the split edges of the cylindrical clip, and project outwardly through the slits I5, to be capable of swinging laterally on their pivots in the manner heretofore described Each arm I8 is provided with an auxiliary fastener or clip 2|, which serves to clamp the side edges of the papers P engaged by the jaws of the main clip, so as to hold the papers in folded or rolled up condition. Such auxiliary clip 2| as shown may comprise a sleeve 22 slidably and turna-bly mounted on each arm I8 and a rod like extension 23 extending longitudinally of the corresponding arm and formed at its outer end with a spring loop 2|, terminating in a ball 2I When the actuating arms have been turned on their pivots to extend longitudinally of the clip body, after clamping the papers and winding them around the clip body 14, the auxiliary clips 2! may be turned and drawn outwardly along the arms until they can be made to clamp the side edges of the rolled up papers as shown in Figures 8 and 9 and therebyretain the latter in rolled up condition.

Various other modifications may be made in the construction of my device Without departing from the spirit of my invention. 1, therefore, do not Wish to restrict myself to the details of the constructions described and shown.

What I claim is:

1. A paper clip comprising a cylindrical split spring shell having recesses extending longitudinally at opposite sides, abutments inside said shell, and jaw actuating arms pivoted inside said shell to said abutments and projecting outwardly through said recesses, said arms being capable of swinging laterally on their pivots.

2. In a spring paper clip according to claim 1 in which said pivots are displaced longitudinally relative to one another to permit said arms of swinging in opposite directions relative to one another.

3. In a spring paper clip according to claim 1 in which said recess-es are displaced longitudinally relative to one another to permit said arms of swinging in opposite directions to one another.

4. In a spring paper clip according to claim 1 in which said abutments are formed by blocks of rigid material borne on opposite sides of the inner face of said shell.

5. In a paper clip the combination with the spring jaws thereof, of jaw actuating arms pivoted to said jaws, and means provided on said arms and capable of clamping the side edges of the papers after the latter have been clamped by and folded or rolled around said jaws.

6. In a paper clip according to claim in which said means consist of auxiliary clips movably borne on said arms.

7. In a paper clip according to claim 5 in which said means are slidably and turnably borne on said arms.

8. In a paper clip according to claim 5 in which said means comprise a sleeve slidably and turnably borne on each of said arms and an extension of said sleeve terminating in a spring clip.
